The river '''Glanduin''' was a river of [[Eriador]] and a northern arm of the [[Gwathló]].

Beginning in the [[Misty Mountains|Hithaeglir]] south of [[Khazad-dûm]], it flowed west-north-west until it was met by the [[Sirannon]] near the old location of [[Ost-in-Edhil]], the capital of the [[Noldor]] of [[Eregion]]. From there the Glanduin flowed westward towards the [[Mitheithel]], which it met in the [[Swanfleet]] marshes (''[[Nîn-in-Eilph]]'') north-east of [[Tharbad]]. There was an old ford across the Glanduin east of the falls that dropped down into the marshy lowlands.<ref name="Partings">{{RK|VI6}}</ref>

Note

The name "Glanduin" applied to the whole river during the time of Eregion and Arnor. However, by the time of the War of the Ring, it only applied to the swift upper course of the river, and usually it was referred to as the Swanfleet river (not River), simply meaning the river that flowed into the Nîn-in-Eilph.[4]
